Quote:Universal Extractor 2 is a tool designed to extract files from any type of extractable file.

Unlike most archiving programs, UniExtract is not limited to standard archives such as .zip and .rar. It can also deal with application installers, disk images and even game archives and other multimedia files. An overview of supported file types can be found here

This program is an unofficial updated and extended version of the original UniExtract by Jared Breland. As the development of the original version has stopped and no update has been published for years, many forks (modified versions, maintained by volunteers from the community) have arisen. This is the most advanced of them, featuring a very long list of enhancements.
